Re: [Gnu3dkit-dev] New core API

Hi,

spending more time on all that some more simplifications might be 
possible:

Maybe this can be internal only, or even be integrated into the context 
class itself?!

Maybe this is too much of OO - should we integrate this functionality 
into the camera itself? In the old 3DKit this design approach resulted 
in some annoying implementation hacks w/o providing additional value in 
terms of usability.

I now think that we should not provide this class in the core API. 
Instead we should make sure that the various actions can be performed 
using multiple threads. Otherwise the API becomes IMHO too heavy.

We might use the RSL here, or at least a similar approach.

Moreover I'd like to hear from you whether you prefer having everything 
packed into an ObjC class or not - think of bounding boxes, bounding 
spheres, transformations and so on... Personally I would go for C 
constructs here, but maybe this is way too "old school"...:-)
